355 EAST KELLOOG BLVD. <br />ST. PAUL, MINNESOTA 55101 <br />ARCHITECTS S12- 291 -020E <br />October 18, 1990 <br />Mr. Joel Hanson, City Administrator <br />City of Little Canada <br />515 East Little Canada Road <br />Little Canada, Minnesota 55117 <br />RE: Pioneer Park Recreation Building <br />Little Canada, Minnesota <br />Dear Mr. Hanson: <br />In response to your request for additional information and back- <br />up regarding the Change Orders for the above referenced project, <br />I submit the following for each Change Order. <br />A.) Hollow Metal. Deduct $65.00. Changing the gauge of exterior <br />hollow metal frames from 14 gauge to 16 gauge due to availability <br />of frames. (Previously Approved) <br />B.) Earthwork. Add $1983.00. These charges are due to soil cor- <br />rections required due to the fact that the original sewer and <br />water stubs were found to be under the shelter area column pad <br />footings. The corrective work was done in response to the requi- <br />rements of the soils engineer, Braun Engineering and Testing. <br />The original stubs were located in anticipation of a future <br />building that was assumed to occupy a site area of only 40'X40'. <br />(Previously Approved) <br />C.) Floor Trusses /Wood Beams. Add $2,589.00. This Change Order <br />actually originated in the Bidding Phase of the Project. As is <br />most common with the design of wood trusses we, as Architects <br />and /or Engineers, give the design parameters in terms of span <br />and depth and anticipated loading. The individual manufacturers <br />of the metal plates that connect the truss components all have <br />their own programs for the engineering and in fact do the act- <br />ual truss design. <br />During the bidding process, floor truss manufacturers made me <br />aware that they could not design a truss to span the full 29' <br />width of the building north of the north stair, nor could they <br />design the girders in the 14" floor depth. (The girders run <br />north and south at the east and west centers and carry the wall <br />and roof even though they are actually located in the floor.) <br />As I had no way of knowing who all of the sub - bidders would be <br />Page 106 <br />
